ROUTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 545,380, dated August 27, 1895.

Application filed March 5, 1894. Serial No. 502,356. (No model.)

To all whom, t may concern:

Be it known that we, CARL SCHRAUB- s'rsn'rne, Jr., and CHARLES R. SCHILLING, of the city of St. Louis, in the State of Missouri,

have invented a certain new and useful Ixnprovelnent in Routing and Channeling Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of to this specilication.

Our present invention relates to certain improvements in machines for routing and fortning channels in difterent objects,'such as engraving-plates and other printing-surfaces,

i5 and our invent-ion consists in features of novelty hereinafter fully described, and pointed outin the claims.

Figure I is part in plan view and part in horizontal section taken on line I I. Fig. Il is :c a detaii elevation. Fig. HI is a perspective View of the drill or tool.

Referring to the drawings, 1 represents a suitable table upon which the plate 2, or other article to be operated upon, is placed, and upon z5 which it is held by means of a strip 3 and clamp 4. The strip and clamp correspond substantially with the strips 7 and the clamps shown in Fig. X of our patent, No. 151,7 74C, issued June 23, 1891.

5 represents the tool secured to a spindle 6, mounted in a suitable frame 7, by which it may be moved back and forth in the operation of the machine. The frame 7 slides or works on the swinging arm 6, which is supported at its outer end on the rail 7a, carried by the table 1. These parts are in substance the saine as the corresponding parts in the patent referred to, and they require no eX- planation.

This invention refers to a combined gage and guide 8, which is hinged, as shown at 9, to a plate 10, made fast to the table 1 by means of bolts 11, having heads ittin g in grooves 12 in the table. The heads are represented by 15 dotted lines at 13, and are larger than the grooves l2, so that while the bolts can be moved lengthwise of the grooves they 'are held from vertical movement. The bolts lit in grooves 14 in the plate lO, so that the plate 5o can be shifted endwise or can be turned at an angle to the length of the table. The

-in the position shown by full lines, Fig. I, or

guide and gage 8 has a rim or roll 15, fitting between ears 16 on the plate 10, and which receives bolts or screws 17, passing through the ears and entering the ends of the roll. The guide and gage has an arm 1S to receive a thumb-nut 19, by which the guide and gage may be adjusted in its vertical position, the lower end of the thumb-screw bearing against the plate 10, and by turning it up or down the vertical face of the gage may be adjusted.

19a is a jam-nut on the thumb-screw. During the operation of the tool the guide and gage is in the position shown in Fig. H, at which time a circular segment 20, secured to the spindle-frame 7, bears against the inner Vertical face of the guide and gage for the purpose of guiding the tool, and it thus serves to guide the tool whether the part 8 is whether it is in the position shown by a dot ted line A, Fig. I, or at some 'other angle. The distance from the pivot 9 of the gage and guide to the point 21 is about equal to the distance from the hinge 9 to the workingpoint 22 of the tool.

When the article to he operated upon is placed on the table, the spindle 6 is swung to one side out of the way and the gage and guide is swung to bring its edge 21 down upon the article to be worked upon, and thus at'- fords a straight edge for adjusting the work or the plate to be worked upon. After the necessary adjustment is finished the clamp 3 4 is applied. The gage is then brought back to the position shown in Fig. H, and the tool being brought into working position with the segment 2O against the inner face of the guide the machine is ready for operation, the tool striking the plate at the point registered by the edge 21 of the gage when the work is being adjusted to position. Should the gage not be perfectly adjusted and bring the out too far from the line to which it was set, the raising or lowering of the screw 19 will push the gage 8 over, and in this manner the operator can gradually adjust the tool.

We claim as our invention- 1. In a channeling and routing machine, the combination of a suitable support, a tool provided with a segment, a plate adj ustably secured to said support and having hinged ICO Vbears against the said segment substantially theretoacombined gage and guide, and which zonta position for gagging the position of the tool and into vertical position for guiding the 1o 1300i, substantiaiy as shownu and descrbef.y 2.
